FAQ

Do I need a bundler or to install dependencies?

No. The hub is a self-contained static site with no build step — there is no package manager or bundler, and the render engines ship as committed browser bundles.

How do I run it locally?

Serve the site root over HTTP, since the hub uses absolute links: run python3 -m http.server 8000 and open http://localhost:8000.

Does the page make any network calls?

No. Mermaid and PlantUML are vendored as local bundles, the game and the English trainer are plain JavaScript with nothing to fetch, so the pages make no external network calls at runtime.
